UNITED STATES MICHAEL P. MURPHY, OF NEW YORK, N. Y. '1.

v v 1,594,896 PATENT- orricsnurnronrme MACHINE.

Application filed August 21, 1920. Serial No. 405,008.

To all whom it may concern:

Be it known that I, MICHAE P. MUR- PHY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented .certain new and useful Improvements in DuplicatingMachines, of which the following is a specification.

My present invention relates to apparatus for making and preservingcopies of letters and other documents.

The objects of the invention are to enable the copying of letters andthe like on a continuous web of copy paper and to facilitate theseverance of said web at the end of the copying operations into sheetsof the proper length.

In the accompanying drawings I have illustrated the invention embodiedin one of its practical and preferred forms and have indicated certainmodifications, but wish it understood that further modifications andchanges may be made without departure from the true spirit and scope ofthe invention as herein defined in the claims.

In the drawings referred to Figure 1 is a broken side view of a copyingor duplicating machine having features of my invention incorporatedtherein;

Figure 2 is a detached perspective viewof a modified form of reel onwhich the copying web is wound;

Figure 3 is a fragmentary top plan view of the reel with a portion ofthe web thereon;

Figure 4 is a sectional view of the same as taken on substantially theplane of line 44 of Figure 3;

Figure 5 is a broken detail view of the modified construction of thereel.

The duplicating machine illustrated in Fi ure 1 is shown as of typicalconstruction embodying a feeding table 7 for the letters, a pair ofcopying rolls 8 and a receiving table 9. The copying rolls are turned bya handle 10 or other suitable means, and the letters or other papers arecopied, in this instance, on a continuous web 11 supplied from the roll12 and passing over a guide roll 12 to and between the copying rolls 8.

The impression is made on this copying web in its passage, for theletter, between the copying rolls. In the machine shown the web is thenpassed about a suitable drying roll 13, being directed to and about thesame by means of guiding rolls 15 and 16.

After the copies are thus made on the web,

the web is wound ona take-up or storage device shown in the form of aroll having end heads 17 and 18 of elongated construction connected atthe ends by the pairsof spaced rods 19 and at the sides by the rods 20.The headsofthe roll are carried by a suitable supportingshaft 21 whichis shown in Figure 1 as driven by a-pulley 22 and belt ing 23 from apulley 24 on the shaft 25 of the copying roll 8; or a chain andsprockets maiy be substituted for the belt and pulleys.

11 Figure 1 I have illustrated how, as the sprockets are made, the webis wound in built-up layers on the storage reel. This reel is preferablyso designed that the sections 11 and 11 of the webbing at opposite sidesof the major axes of the reel are each approximately equal to the lengthof the letters or other papers ordinarily copied. This means that aletter length of the web will stand at each side of the reel, so that bysevering the web on the major axes the web will be separated intoseparate sheets, each carrying a copy of the letter.

This separation of the web into letter size sheets is provided for byslotting the ends of the reel heads between the spaced web-supportingrods 19, as indicated at 26 to enable the insertion of a knifeor othercutting in strument beneath the web at these two diametrically oppositepoints. One of these lines of severance is indicated by the dashand-dotline 27 in Figure 3.

From the foregoing it will be seen that as the letters or other papersare passed through the machine copies will be automatically transferredto the web, and this web, after being dried, will be wound on thetake-up reel. At the end of adays work or at any other time the lettercopies may be separated and removed from the machine by simply severingthe web passing over the spaced supporting-rods of the reel, the slotsin the ends of the reel facilitating this operation and serving as endsfor the severing or cutting tool.

At times it may be found necessary to adjust the reel for the purpose ofproperly positioning the letter copies at the opposite sides of thelines of severance. This may be accomplished by adjusting the supportingrods 20 radially or toward and away from the centre of the reel. This isprovided for in the construction shown in Figures 2 and 5 by mountingthe ends of the rods in substantially radial slots 28 in the heads ofthe a reel and by securing the same at variously adjusted positions insaid slots by thumb screws or other clamping devices '29. It will beseen that by adjusting these rods outward-or inward in such bearings thelength of the section of webbing at one side or the other of the reelmaybe increased or diminished as required. This makes the inventionreadily adaptable for letters or documents ofdi'flf erent length andallows for, adjustmentsto properly register the copies on the reel Iclaim;

1. A reel vfor a web of copying material having-end heads provided atdiametrically opposite points with outwardly opened guide slots,: and"web-supporting rods connecting said end heads and disposed at oppositesides of the guide slots to support superi1nposed layers of the Web inposition to be severed by a cutting implement inserted in the slotsaforesaid.

2. A reel for a web of material having end heads provided with outwardlyo ened slots, web supporting rods connected with said end heads, certainof said rods being disposed at opposite sides of the slot to supportlayers of the material in position to be severed by a cutting implementinserted within the slot and beneath the material, and other of saidsupporting rods being radially adjustable on the heads to vary the sheetlength of the material on the reel.

In testimony whereof I affix my signature.

MICHAEL P. MURPHY.
